PATENT \VILLIAM R. KINNEAR, OF'OOLUMBUS, OHIO.

METAL DOOR, PARTITION, 800.

SPECIFICATION forming part of Letters Patent No. 603,106, dated April 26, 1898.

Application filed May 27, 1897. Serial No. 638,387. (No model.)

To all whom it 12mg concern.-

Be it known that I, WILLIAM R. KINNEAR, a citizen of the United States, residing at Colu rnbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Metal Doors, Partitions, &c.; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention pertains more particularly to the class of doors, partitions, shutters, or blinds that are horizontally movable and roll upon a vertically-arranged roller.

My invention consists in the improved construction of such devices, substantially as hereinafter described, whereby their operation is rendered easier and the structure made more durable and less liable to derangement than those heretofore produced.

In the annexed drawings, Figure 1 is a View illustrating the inner side of the curtain, the casing for the roller being in sectional view, all the parts being broken out horizontally along the middle. Fig. 2 is a horizontal sec tion al view illustrating one form of device for guiding the curtain onto the track, the curtain-roller being removed. Fig. 3 is a detail illustrating, on a larger scale, the form of ourtain-guiding device shown in Fig. 1. Fig. 4

is a detail illustrating a modified form of de-' vice for guiding the curtain onto the track. Fig. 5 is a detail inside and top view illustrating a modified form of hanger; and Fig. 6 is a detail in top, side, and end views illustrating small trucks or slides in which the curtain-roller may be j ournaled.

Like characters of reference in the different views designate corresponding parts.

will have laterally-extending projections 2 and 2, that interlap, so that each casting or plate supports an adjoining one, thereby maintaining the slats in proper vertical position with respect to each other. The interlapping projections 2 and 2 are made of such form and area that the slats may be turned upon their connected edges without separatin g the said projections. Arranged in the upper part of the door, window, or other opening is a track 4, formed of thick sheet metal, which may also be bent to form a hood and guard 4: above the same. At one side of the window or door opening in a suitable casing 6 is vertically arranged a roller 5, to which the curtain is attached and upon which it may be wound. The lower end of this roller is provided with a horizontal disk 5, having its upper side tapered or inclined toward the axis of the roller, so that as the curtain is rolled onto the roller the major portion thereof shall be slightly lifted to elevate the lower part of the tread of the wheels or sheaves 3 above the horizontal plane of the edge of the track.

The roller 5 may be journaled either in suitable stationary bearings or in sliding bearings, substantially as illustrated in Fig. 1, and where the curtain is unusually large and heavy the roller may be supported in small wheeled trucks or slides '7, (see Fig. 6,) that run in grooves 8, formed in the upper and lower ends of the casing. Instead of wheeled trucks, however, slide-blocks without wheels fitting nicely in the grooves 8 may be employed.

The device for automatically guiding the unrolling curtain onto the track may be either stationary, as illustrated in Figs. 1, 2, and 3, or pivoted or hinged, as illustrated in Fig. 4.

In both instances it is shown to have flared or rounded side walls 9 and 9 and a flared or rounded bottom wall 9. The bottom wall 9 will have a short part of the track 9 the inner end of which is rounded and the outer end of which is adjacent to the end of the stationary part of the track. The round bottom 9 of the mouth will also have a rounded projecting edge that will tend to guide the curtain, so that the wheels orsheaves shall run onto the short part of the track, whence they will properly run onto the stationary part of the track.

In the modified form of guide for the unrolling curtain, as shown in Fig. 4, the mouth portion corresponds in every essential feature to that just described, except that in this instance it is provided with pintles or studs 10' and 10 at its upper and lower sides in line with each other and substantially in line with the outer end of the short part of the track, so that the mouth may be oscillated without materially displacing the said end of the short track. Thepintles or studs 10 and 10 are supported in suitable bearings or sockets fastened by means of plates 11 and 11 near the curtain-slot in the wall of the casing. In this form of guide the mouth adjusts itself automatically to the nnrolling curtain whatever be the size of the roll.

In Fig. 5, showing a modified form of plate or casting 2 and hanger, there is but one projection 2 and 2 on each side, and these are arranged to interlap, so that the slats between the curtains are supported in proper vertical position between the hangers.

Any obvious means for rolling or unrolling the curtain may be provided. At the upper end of the roller I have shown an affixed drum, to which may be attached and wound or unwound a rope or chain (not shown) for rotating the roller.

My improvemen ts,while especially design ed for metallic curtains, are equally useful in curtains of other materials.

My invention, as herein shown and described, is susceptible of modification Without departing from the principles thereof.

What I claim, and desire to secure by Letters Patent, is

1. In combination with a horizontally-movable, flexible curtain, a vertically-arranged roller having a disk at its lower end with an inclined upper surface, substantially as described.

2. In combination with a horizontally-movable, flexible curtain, having hangers, a track upon which said hangers run, a vertically-arranged roller having at its base a disk with an inclined upper surface upon which said curtain is supported when the curtain leaves the track, substantially as described.

3. In combination with a curtain-roller, a flexible curtain connected to said roller,

wheels or supports for said curtain, a track upon which said wheels or supports run, consisting of a stationary part and a movable part near said curtain-roller for automatically guiding said wheels or supports onto the stationary part, substantially as described.

4:. In combination with a curtain-roller, a flexible curtain connected therewith, wheels or supports for said curtain, a track upon which said wheels or supports run, consisting of a stationary part 4 and a flared mouth constructed to guide the curtain wheels or supports onto the track, substantially as described.

5. In combination with a curtain-roller, a flexible curtain connected therewith, wheels or supports for said curtain, a track consisting of a stationary part 4, and a mouth for guiding the wheels or supports onto the track having Walls 9 and 9, wall 9 and projecting edge 9, substantially as described.

6. In combination with a curtain-roller, a flexible curtain connected therewith, wheels or supports for said curtain, a track upon which said Wheels or supports run, consisting of a stationary part 4, and a mouth adapted to guide said wheels or supports onto said track hinged or pivoted at the end of said track, substantially as described.

7. In combination with a casing having a guide or way 8, a roller and curtain thereon, said guide containing a bearing or support for the roller-spindle arranged and adapted to freely move in said guide or way, whereby the roller is automatically adjusted in its position with respect to the curtain inlet and outlet as the curtain wound or unwound, substantially as described.

8. In combination with a curtain-roller, a flexible curtain connected therewith, wheels or supports for said curtain, a track consisting of a stationary part 4, and a mouth for guiding the wheels or supports on to the track having wall 9 with edge 9 and a flaring wall 9, substantially as described.

In witness whereof Ihereunto set my hand this 20th day of May, 1897.

WILLIAM R. KINNEAR.
